Had a different slant to this. A few months ago I texted a WG, but we didn't get anything sorted after a few texts. Then about a month ago, got a text from an 'Ariel' a WG from Derby, telling me she's avail, with a link to her profile, with rates, etc etc.
If this wasn't bad enough, she had taken over the phone from the girl I originally texted and was punting for business by texting all the numbers in it. Luckily I use a punting phone, but imagine if I hadn't have done. The text itself would have got anyone into deep trouble if the wrong person saw it.
I texted her back noting that this was un-professional and remove my number. A week later she sent another text. I was livid. So I booked an appt over the phone and 'failed' to turn up, then phoned her to ensure she removed my number. So far, no more texts, but makes you realise why you NEED to use a separate phone for punting.
